International mediation can have a significant impact on a country's soft power, which is the ability to influence others through attraction and persuasion rather than coercion or force. Here are some ways in which international mediation can influence a country's soft power:
Increased visibility and recognition: When a country engages in international mediation, it gains visibility and recognition on the global stage. This can help increase its soft power by raising awareness of its values, culture, and diplomatic capabilities.
Promotion of peaceful conflict resolution: International mediation is often associated with peaceful conflict resolution, which can enhance a country's reputation as a mediator and peacemaker. This can increase its soft power by demonstrating its commitment to international norms and values.
Strengthened relationships: International mediation can help strengthen relationships between the mediating country and the conflicting parties. This can increase the mediating country's soft power by building trust and goodwill among different actors.
Enhanced credibility: Successful international mediation can enhance a country's credibility as a mediator and as a leader in promoting international peace and security. This can increase its soft power by demonstrating its ability to resolve complex issues and bring about positive change.
Improved standing in international organizations: Countries that engage in international mediation can also improve their standing within international organizations such as the United Nations. This can increase their soft power by giving them greater influence and authority in shaping global norms and policies.
I'll suggest a reading of articles on the soft power of Nigeria and South Africa's conflict mediation efforts in Africa. Authors like Olusola Ogunnubi, Christopher Isike, Oluwaseun Tella, Victor Ojakorutu have published extensive on this subject matter.
